The present invention relates to an ocher block attached to a tile and a method of manufacturing the same, and more particularly, by mixing an alkaline reinforcing agent, an acid additive, and a natural resin with ocher to attach the tile to an ocher block having improved strength and durability, and then constructing it. The present invention relates to an ocher block having a tile attached thereto, and a method of manufacturing the same.

In general, ocher has been widely used as a building material for building walls, floors, and fireplaces in kitchens. In addition, it has been used as an arable land for redevelopment, earthenware, and tile ceramics, as well as for arranging rice fields for improving characteristics, fish farm floors, and cowshed floor coverings.

In addition, the efficacy of loess includes the effect of far-infrared emission. Ocher is absorbed by the human body by radiating beneficial far-infrared rays, so the metabolism is smooth and blood circulation is active, thus preventing the aging of the human body, promoting metabolism, and eliminating chronic fatigue. In particular, ginseng and ginkgo biloba grown in loess is very good quality, fermentation of kimchi, soybean paste, soy sauce, etc. under the surface of the loess, the fermentation is active, the quality is improved.

Despite these many advantages, there is no suitable technology that can be utilized as a building material by commercially mass-producing ocher. Therefore, most of the bricks manufactured using building materials are currently made of concrete as the main raw material.

However, concrete is excellent in terms of bonding strength, but it is harmful to human body and has a low heat insulation effect, so heat loss is large, and when it is discarded or lost due to durability, it is adversely affected by the toxicity of concrete. There is a problem that is not environmentally friendly such as Mitch.

In addition, when a structure including a brick is made of pure ocher only, a problem arises in that strength and durability are reduced.

In addition, in the conventional tile construction, after constructing the construction surface by pouring concrete, the construction period is long because the construction surface has to wait until the construction surface is cured and then attach the tile to the construction surface using adhesive, resulting in construction cost There is a problem that rises. Therefore, there is a need for improvement.

The present invention has been created by the necessity as described above, by increasing the construction period by attaching the tile after curing the construction surface, the cost is increased, and the surface wear degree and durability of the ocher block to which the tile is attached to enhance An object of the present invention is to provide an ocher block and a method of manufacturing the same.

In addition, an object of the present invention is to provide an ocher block with a tile and a method of manufacturing the same, which can prevent environmental pollution caused by attaching the tile to a brick or a wall using concrete.

According to the present invention, there is provided a method of manufacturing a loess block to which a tile is attached: a first step of drying the ocher to have a moisture content of 10 to 15%, a second step of pulverizing the dried loess, and The third step of obtaining an ocher mixture by adding an alkaline reinforcing agent, an acid additive, water and a natural resin, the fourth step of molding the ocher mixture into a mold and drying the ocher block produced through the fourth step The fifth step and the sixth step of attaching the tile using the adhesive on the surface of the ocher block.

Preferably, the tile is molded using the ocher mixture as a raw material, and the corner portion of the upper side of the tile is rounded.

In addition, the adhesive is a mortar which is an inorganic binder, and the mortar includes at least one of lime mortar, resin mortar, and ocher mortar.

In the second step of crushing the loess, the loess is based on 100 parts by weight of ocher, and 25 to 35 parts by weight of loess, ground to particles of 0.5 mm to 1 mm, and loess 45 to particles of 1 mm to 2.5 mm. 55 parts by weight, composed of loess having a composition ratio of 15 to 25 parts by weight pulverized into particles of 2.5mm to 4mm.

And, in the third step, the ocher mixture, ocher 60-80 parts by weight, the alkaline reinforcing agent is 5 to 20 parts by weight, the acid additive is 2.5 to 8 parts by weight, the natural resin is 1 to 6 parts by weight and other The remaining amount will contain water.

And, the alkaline reinforcing agent is characterized in that it comprises at least one or more of limestone, gypsum or white cement.

And, the acidic additive is composed of at least one of sulfonic acid or citric acid.

In addition, the natural resin is to use at least one or more of the gambuji and latex and water-soluble balsam resin, which is the sap extracted from the red pepper family.

In the fifth step, the ocher block is dried for 20 to 40 days in a natural state of 12 to 18 degrees.

In the fifth step, the ocher block is further provided with a process of drying in a drying apparatus for 20 to 28 hours at a temperature of 15 to 25 degrees before drying in the natural state.

In addition, in the sixth step, the adhesive surface is adhered to the adhesive surface of the tile and the adhesive surface of the ocher block in a state in which a fixing groove is formed.

The ocher block to which the tile is attached according to an embodiment of the present invention is manufactured by the method of manufacturing the ocher block to which the tile is attached.

Hereinafter, with reference to the accompanying drawings will be described a loess block and a manufacturing method attached to the tile according to an embodiment of the present invention. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

1 is a flow chart illustrating a manufacturing method of an ocher block with a tile according to an embodiment of the present invention, Figure 2 is an exploded perspective view of the ocher block with a tile according to an embodiment of the present invention, Figure 3 is a side view of Figure 2, Figure 4 is a side view of the ocher block attached to the tile according to another embodiment of the present invention.

As shown in Figure 1, the manufacturing method of the ocher block according to an embodiment of the present invention has a first step (S10) for drying so that the moisture content of ocher within 10 to 15%.

Drying the ocher is to allow the ocher to be mixed with the other mixture in the correct composition ratio.

If the moisture content of the loess is more than 15%, the loess becomes cold and it is difficult to mix with other materials.

When the moisture content of the loess is 10% or less, the loess is blown to generate dust.

Therefore, the moisture content of the loess is preferably dried to 10 to 15%.

And, it has a second step (S20) of grinding the dried ocher.

The ocher is uniformly pulverized into particles of 0.5 to 4 mm to be easily mixed with other materials, and more preferably, the ocher is pulverized into particles of 0.5 to 1 mm.

As the ocher is uniformly pulverized as described above, the crushed ocher is more uniformly mixed with other materials.

When the particles of ocher become 0.5 mm or less, the particles are too small to increase dust, and when the particles of ocher are 4 mm or more, uniform mixing with other mixtures is difficult.

In the second step of crushing the ocher according to another embodiment of the present invention, the ocher is 25 to 35 parts by weight of the ocher crushed into particles of 0.5mm to 1mm, particles of 1mm to 2.5mm with respect to 100 parts by weight of ocher It is composed of loess having a composition ratio of 45 to 55 parts by weight of ocher, and 15 to 25 parts by weight, which are ground to particles of 2.5 mm to 4 mm.

That is, the ocher is composed by crushing the ocher with particles of 0.5mm to 1mm, crushing the ocher with particles of 1mm to 2.5mm, and crushing the ocher with particles of 2.5mm to 4mm in the weight ratio. Preferably, the size and weight ratio of the ocher particles may vary within the technical concept of allowing the small particles of loess to enter between the larger particles of loess.

The ocher crushed into particles of 0.5 mm to 1 mm enters the space between the particles of ocher crushed into particles of 2.5 mm to 4 mm, which are relatively large particles, and particles of ocher crushed into particles of 1 mm to 2.5 mm, thus making the ocher more dense. Having a tissue increases durability and strength.

The ocher pulverization method as described above may be applied in a variety of techniques within the technical spirit of compacting the tissue while being easy to mix with other mixtures in addition to the method described above.

The second step (S30) to obtain an ocher mixture by adding an alkaline adjuvant, acid additives, water and natural resin to the ground ocher crushed through the second step.

Preferably, the ocher mixture, ocher 60-80 parts by weight, the alkaline reinforcing agent is 5 to 20 parts by weight, the acid additive is 2.5 to 8 parts by weight, the natural resin comprises 1 to 6 parts by weight, The ocher mixture is made from water except for alkaline adjuvant, acid additive and natural resin.

The alkaline reinforcing agent is configured to include at least one or more of limestone, gypsum or white cement, in addition to the material having an alkaline component is used as an alkaline additive according to an embodiment of the present invention to reinforce the stiffness of the ocher block 10. .

Preferably, limestone and gypsum are mixed in a ratio of 2 to 1 to most preferably constitute an alkaline reinforcing agent, but is not limited thereto, and reacts with an acidic additive while reinforcing the stiffness of the ocher block 10 and the ocher block 10. Various changes will be possible in the technical ideas that make the organization more dense, including the mixing of different proportions including white cement or the use of alternative materials.

The back cement is also called white portland cement, and has excellent early strength and durability, and excellent coloring power due to the appearance of whiteness.

In addition, the acid additive comprises at least one of sulfonic acid or citric acid, and in addition to this, a material having an acid component may be used as an acid additive according to an embodiment of the present invention.

Salt and water are generated as the acidic additive is added and reacted with the alkaline adjuvant.

The alkaline adjuvant and the acidic additive are uniformly mixed with the loess, and as a result, water is generated by the neutralization reaction of the alkaline adjuvant and the acidic additive, and an anion being an acidic ion of the cation and the acidic additive of the alkaline adjuvant. Are combined with each other. As a result, the bond is more firmly combined with the molecules of the loess, thereby increasing the viscosity, thereby further improving durability.

On the other hand, the water generated during the neutralization reaction, because it is uniformly spread in the interior of the loess serves an additional role to increase the stiffness by rubbing the tissue. That is, since water generated during the neutralization reaction is supplied to the part of the ocher mixture that is not supplied sufficiently to the inside of the ocher, the alkaline adjuvant and the acid additive, it serves to make the tissue more dense.

In addition, limestone and gypsum constituting the alkaline reinforcing agent may be used as a cement material, and the alkaline reinforcing agent may be mixed with the loess to further increase the stiffness of the ocher block 10.

On the other hand, in obtaining the ocher mixture, the stiffness and durability of the ocher block 10 is significantly lowered if the alkaline adjuvant and the acid additive is not used, the ocher block 10 according to the embodiment of the present invention is an alkaline adjuvant and acidic The use of additives is most preferred.

The natural resin can be used by selecting the water-soluble balsam resin (balsam resin) extracted from a plant called latex (Latex), Gamboge, balsam, etc. extracted from the rubber tree according to the color and use, and the molecular weight between ocher Gamji is a strong force to increase the binding force is used as a natural resin according to an embodiment of the present invention, if necessary, other latex or balsam resin can be used as a natural resin according to an embodiment of the present invention.

The natural resin serves as a curing agent to promote curing while increasing the hardness of the ocher mixture.

It has a fourth step (S40) for molding by putting the ocher mixture passed through the third step into a mold.

Vibration and pressure is applied to the mold for molding the ocher mixture, and molding is performed. Preferably, the molding is performed by applying a vibration of 2000 to 4000 VPM and a pressure of 200 kg / cm 2.

The mold has a shape for molding the ocher block 10, but of course, the mold shape can be modified in order to mold the ocher products having various shapes.

In addition, the vibration and pressure values may vary within the technical concept of applying the vibration and pressure to the mold to form the ocher block 10 having a predetermined shape.

It has a fifth step (S50) for drying the ocher block 10 generated through the fourth step.

In drying the ocher block 10 is dried and cured for 20 to 40 days at a natural state temperature of 12 to 18 degrees, preferably 15 to 28 days to dry, but limited to the temperature and the number of days Of course, the numerical values of the temperature and the number of days can be changed by various embodiments.

The ocher block 10 is dried at 15 to 25 degrees in a drying apparatus for 20 to 28 hours before drying in the natural state, preferably drying at a temperature of 20 degrees.

The temperature in the drying apparatus has a temperature higher than the temperature of the natural state, preferably has a temperature range of 19 degrees to 23 degrees, but is not limited to the temperature value and various numerical changes are possible according to the embodiment. Of course.

2 and 3, the fifth step (S60) for attaching the tile 30 to the surface of the dried ocher block 10 through the fifth step.

An adhesive 20 is applied to the adhesive surface of the ocher block 10, and the tile 30 is fixed to the ocher block 10 by contacting a lower adhesive surface of the tile 30 on the adhesive 20.

Ocher mortar, which is mainly made of natural material ocher, may be used as the adhesive 20 according to an embodiment of the present invention.

The ocher mortar is a functional health mortar that is excellent in humidity control, antifungal, deodorization, and far-infrared radiation.

The ocher mortar is easy to construct and environmentally friendly by using a mixture of hardener and water such as natural resin in the ocher.

The tile 30 is molded using the ocher mixture as a raw material.

The tile 30 is coated with a glaze on the surface of the ocher plate after molding the ocher mixture in the shape of the ocher plate.

In addition, when the glaze coated on the surface of the ocher plate is cured, an aqueous solution of titanium sol photocatalyst antimicrobial agent containing silver or copper may be further coated on the ocher plate to provide antibacterial and airborne effects.

The ocher plate is cut to fit the outer shape of the tile 30 to be used as the tile 30 according to the present invention.

The tile 30 has a corner portion of the upper side is rounded to form a curved portion 34.

The curved portion 34 is a curved surface to prevent a safety accident that may be caused by a user or a builder in contact with the tile 30, integrally formed when the tile 30 is formed in a mold, The curved portion 34 is formed in various ways such as formed by the post-processing of the tile 30.

The size of the tile 30 may be smaller than the size of the ocher block 10, but this is merely exemplary, and the size of the ocher block and the size of the tile is the same, or the size of the tile than the size of the ocher block The size and shape of the tile may be variously changed according to the use purpose and environment of use, such as a large size.

In addition, the tile 30 according to an embodiment of the present invention may use a general tile, it will be preferable to use a tile 30 molded from the ocher mixture as a raw material.

According to another embodiment of the present invention, as shown in Figure 4, in order to strengthen the tile 30 in contact with the ocher block 10, the adhesive surface of the tile and the corresponding ocher block 10 Fixing grooves 32, 12 are formed on the adhesive surface of the).

Since the hardened adhesive 20 is inserted into the fixing groove 32 of the tile 30 and the fixing groove 12 of the ocher block 10, the tile 30 is pressed even in the lateral direction. The adhesive durability of) is further increased than before.

The number of fixing grooves 32 of the tile 30 and the fixing grooves 12 of the ocher block 10 may be increased or decreased depending on the size and use of the tiles 30 and the ocher block 10.

The ocher block 10 having the tile 30 according to an embodiment of the present invention is manufactured by using the ocher block manufacturing method to which the tile is attached.

The ocher block 10 and the tile 30 thus manufactured have sufficient durability to be used as a building material, which will be described based on experimental values tested by the Korea Testing Institute.

Experiment  Yes

The ocher block 10 and the tile 30 are formed of an ocher mixture having the same composition ratio, so that only the ocher block 10 is tested because of similar physical properties such as bending fracture load and compressive strength. Based on the experimental values, the physical properties of the ocher block 10 having the tile 30 can be easily estimated.

The test sample was made by mixing ocher, water, and alkaline adjuvant (lime, gypsum) into an ocher block. Sample 1 was formed by mixing water and acidic additives (sulfonic acid and citric acid) into ocher block. 2, which is formed into an ocher block by mixing water with an alkaline adjuvant and an acidic additive in loess, and is called Sample 3, and formed into an ocher block by mixing water with a natural resin, an alkaline adjuvant and an acid additive in ocher. It is called.

The samples 1 to 4 are tested by uniformizing the length to 210mm in length, 114mm in thickness to 60mm, and each sample is manufactured and tested for 10 samples, and the average values are shown in Table 1 below. As shown.

 Test Items  Sample 1  Sample 2  Sample 3  Sample 4  Bending failure load (N)  When drying  350  270  480  530  When wet  210  162  289  319  Compressive strength (N / ㎠)  2048  1579  2808  3101

* The bending breaking load and the compressive strength have a ± 2 ~ 3% error range.

As described above, sample 2 mixed with water and acidic additives in yellow soil had the lowest bending fracture load value and compressive strength value, and sample 1 mixed with alkaline reinforcing agent for strength reinforcement showed higher bending fracture load value than sample 2. The compressive strength value is higher, but the bending fracture load value and the compressive strength value are lower than those of the sample 3 containing water, an alkaline adjuvant, and an acid additive in the loess.

The bending load and the compressive strength value of the sample 3 are higher than those of the sample 1 or the sample 2, and the bonding strength of the loess blocks is increased by the reaction between the alkaline reinforcing agent and the acid additive to improve the strength and durability of the ocher block. Because.

In addition, it can be seen that the sample 4 mixed with water, an alkaline adjuvant, an acid additive, and a natural resin in ocher has a higher bending fracture load and a higher compressive strength than the sample 3, which is obtained by adding a natural resin to the alkaline adjuvant and an acid additive. The linkage force between the loess molecules is further increased to increase the hardness of the loess block, thereby promoting hardening.

As described above, the ocher block 10 formed using the ocher mixture in which water, natural resin, alkaline adjuvant and acid additive is mixed with ocher is measured to have higher bending breaking load and compressive strength than ocher block produced under other conditions. It can be seen that it has improved durability and strength.

Therefore, the bending fracture load and the compressive strength of the tile 30 having the same composition as the ocher block 10 and the ocher block 10 to which the tile 30 is attached are attached to the tile manufactured under different conditions and the tile. It can be seen that it has a higher measured value than one ocher block, and the ocher block attached to the tile according to the present invention has improved durability and strength than the ocher block attached to the tile manufactured under other conditions.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand.
